Parameters
pSrc
Pointer to the source image ROI.
srcStep
Distance, in bytes, between the starting points of consecutive lines in the source image.
pDst
Pointer to the destination image ROI.
dstStep
Distance, in bytes, between the starting points of consecutive lines in the destination image.
dstRoiSize
Size of the source and destination ROI, in pixels.
maskSize
Size of the filter kernel.
borderType
Type of border. Possible values are:
ippBorderConst
Values of all border pixels are set to a constant.
ippBorderRepl
Border is replicated from the edge pixels.
ippBorderInMem
Border is obtained from the source image pixels in memory.
Mixed borders are also supported. They can be obtained by the bitwise operation
OR
 between any of the
ippBorderRepl
,
ippBorderConst
, or
ippBorderMirror
 values and the
ippBorderInMemTop
,
ippBorderInMemBottom
,
ippBorderInMemLeft
,
ippBorderInMemRight
 values.
borderValue
Constant value to assign to pixels of the constant border. This parameter is applicable only to the
ippBorderConst
 border type.
pBorderValue[3]
,
pBorderValue[4]
Pointer to constant values to assign to pixels of the constant border. This parameter is applicable only to the
ippBorderConst
 border type.
pBuffer
Pointer to the work buffer.
Description
Before using the
ippiFilterMaxBorder
 and
ippiFilterMinBorder
 functions, you need to compute the size of the work buffer
pBuffer
 using the
ippiFilterMaxBorderGetBufferSize
 or
ippiFilterMinBorderGetBufferSize
 functions, respectively.
These functions operate with ROI (see Regions of Interest in Intel IPP).
The
ippiFilterMaxBorder
 and
ippiFilterMinBorder
 functions apply the maximum/minimum filters, respectively, to the source image ROI. The size of the source image ROI is equal to the destination image ROI size
dstRoiSize
. The values of border pixels are assigned in accordance with the
borderType
 and
borderValue
 parameters. The kernel size of the filter is arbitrary and depends on the
mask
 value.
The anchor cell is the center cell of the kernel, highlighted in red. The anchor cell is defined as:
x
=(
maskSize.width
 - 1)/2
y
=(
maskSize.height
 - 1)/2
where
(
x
,
y
) are cell coordinates.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error when one of the specified pointers is
NULL
.
ippStsSizeErr
Indicates an error when
dstRoiSize
 is negative, or equal to zero.
ippStsBorderErr
Indicates an error when
mask
 is less than, or equal to zero.
ippStsBorderErr
Indicates an error when
borderType
 has an illegal value.
